Winziger, wirkungsgradstarker LED-Treiber mit integrierter Schottky-Diode kann bis zu zehn weiße LEDs ansteuern

(PresseBox) (Ismaning, )
Linear Technology präsentiert den LT3591, einen wirkungsgradstarken Konstantstrom-Treiber für weiße LEDs in einem nur 2mm x 3mm großen DFN-Gehäuse. Der LT3591 enthält eine integrierte Schottky-Diode, das spart Kosten und Leiterplattenfläche. Eine einzigartige, high-seitige LED-Strom-Messschaltung ermöglicht es, die Katode der LED direkt an Masse anzuschließen; eine separate Rückleitung für die Strommessung ist dadurch überflüssig. Der LT3591 kann beim Betrieb an einer Li-Ion-Einzelzelle bis zu zehn weiße LEDs mit einem Wirkungsgrad von mehr als 78% ansteuern. Er arbeitet mit einer Schaltfrequenz von 1MHz, das erlaubt die Verwendung winziger Induktivitäten und Kondensatoren und hält das Schaltrauschen von kritischen HF-Frequenzbändern fern.
